To celebrate the launch of Modern Warfare 2's Stimulus Package earlier this week, Microsoft is offering a free piece of gear for your Xbox Live Avatar. It's a set of night vision goggles.

The goggles can be downloaded by any Xbox Live users. It doesn't matter if you purchased the Stimulus Package or even Modern Warfare 2. All you need is a desire to help your Avatar see in the dark.

The free offer ends on April 4th at 12 PM PST. After that, they'll likely still be available but for a small fee. Whatever that fee ends up being, it'll be a lot smaller than the amount you spent on real MW2 night vision goggles.
